Applicatipn Bled January 9,

v'To all whom it may concern:

Be it known that we, CARLTON RAY MAB- LEY and GUsrAvE E. FRANQUIST,citizens of the United States, and both residing in the borough ofManhattan, city, county, and State lot New York, have invented certainnew and time it is extremely diflicult, to renew the parts of the clutchfor the reason that the necessities of construction of automobiles l -1ssu'ch that the space in which the parts are contained is" very limited,4and in order to get at the clutch, numerous parts must beremoved,`causing trouble when the machine is put together again, owingto the difliculty of alining the various parts. In addition, it is quiteinconvenient to take the machine apart whenever an accident happens tothe c utch: Clutches made in accordance with this'il'lvention canreadilybev removed and put in place without the necessity of taking outthe main shaft of the machine.

In' the accompanying drawing is shown` a construction inwhich ourinvention embodied.

This shaft h rests iu a bearing isecured to the iywheel by the .bolts The hollow shaft it is capabie ot'revolving in the bearing i. 'l'nclosed' inthe hollow shaft h isa spring.zo which bears against a sliding sleevel'into which latter l a pin m isfitted, which pin passes through slots o in the shaft L into sleevef, sothat the expansion ofspring on the pin "m tends to move-the sleeve fand: the said shaft -h inopposite directions longitudinally to clutchthe flywheel and the driven shaft p.. The shaft AND GUsTAvEExE-EANQUIST, oE-NEw YoEK, N. Y., AssIGNoEs, BY i CONTINENTALAu'ruvionnn COMPANY, A-coRroRarroN or h is bolted to shaft p by bolts gpassing,"

"through couplings non both shafts.l The sleeve fis surrounded by aballrace s` hav ing suitable trunnions t for the operating lever '11 theballs running on ,the bearing plate o.' Atlthe end-of the s haftp is athrust bearing w; this thrust bearing w is intended to resist anylongitudinal movements of the shafts p and-htoward fthe fly- Wheel.Another thrust 'bearing :l: is `provided for .the purpose ofneutralizing the;

strain of the spring lc, which, pulling upon the clutch, tends to drawlthe iiywheel toward the clutch and cause apulling strain This thrustbearing balances the powerof the spring.

' ln ordinaryconstructions,` great diiiiculty is experiencedv inremoving -the lclutch to reair its bearing, and bythis invention, suchifficultiesare overcome, and the removal of the clutch'faeilitated.lnorder to remove the clutch, it is only necessary to remove the boltsc, y' and which hold the friction rin b, clutch d and t e bearing 'i solthat'the. sha t 7L and the parts carried thereby canbe lifted outwithoutl disturbing the engine bearings or the driven shaft pl It isobvious that if the bolts holding the friction ring l' are loosened, thespring will force the sleevef and clutch d' back vas faras the slot inthe hollow shafthwill permit.-

The bolts whiclihold the bearing are easily reached through apertures inthe movable member d. The thrust bearing a and the icc bearing 'i arelubricated by means'of a tube y coincident with the axis of the hollowshaft 71,. This tube y is secured in Zplacefby seating the same in thesliding-piece -Ahf'oil-hole is drilled inthe key` m to meet the hole intube y. f

in Figs. 2 and 3, we have shown the mode o f mounting the parts to theframe of an automobile. ln this, 1 indicates th engine, .2 the mainframe of the machine, 3 the rock shaft '5 for the operating leversu,-the said rock shaft being suitably suspended from the main frame ofthe machine by brackets 4 in the usual manner. After making thenecessary repairs tothe clutch, it may be replaced in the machine, andthus it will be seen that it is unnecessary to take the machine a art orto take the transmission or driven s aft out of the machine. 1

For the purposes of this application,we shall c 1,5 regard the shaft a.as the driving shaft, ,and

Vthe shaft as the driven shaft. It will be understood, however, thatourV improvement ma be applied in any .situation where it is un esirabey to remove thedriving or driven 2,0- shaft'from the machine,but'wherein'it may be desirable to use aconstruction wherein the vpartsshall all be accessible forinspection or removal.

' It will be seen thatthe arrangement of the 2,'5v detachable drivingclutch member on the flywheel, together with the detachable thrust'bearing on the end of the intermediateshaft l enables the entire clutchmechanism to be rel moved ,without disturbing anyvother parts.

3o Furthermore, the alinement of parts will beY preserved when they areagain' brought together after the clutch has for any reason,-beenremoved In the lconstruction herein described7 the movable clutchmember is normally moved by the spring, in engaging,

away from the fly wheel, and when the. bolts ',c are removed, the pin mwill move to the end ftheslots o. u At this point, the spring is heldagainst further expansion and, upon re- 40 moving the. bolts and 'qthe'intermediate shaft, to etherV with the spring, the driving pin m andthe clutch ring b can e removed in their'en-tirety, and then the ring bcan be separated from the other parts. A further '45 feature ofadvantage resides in the provision of the oiling devices hereindescribed', whereg vby the thrust 'bearing at the end of the driv- `inglshaft is efficiently lubricated and prevented from becoming overheatedwhen the clutch is running loose, or partially engaged,

. as when starting ,a'vehiclei l Havin thusdescribed our invention, wedeclare t at what we claim as new and desire lto secure by LettersPatent, is,- v

' 1. `In an automobile, the combination of a driving'gear and a shaftcomprised in part by a clutch member, a sleeve supportin said clutchmember, a' hollow shaft on whic said sleeve is adapted to slidelongitudinally, a 6o sprin device contained within the said ho l low saft for moving the clutch member in one direction, the said hollow shaftbeing connected Aat each end toV other sections of shafting and inalinement therewith, the said 6,5 hollow shaftand its supported partsbeing removably secured by such connections in such lspring devicecontained .within the hollow aft, means connecting the said sleeve withsaid 'spring' device whereby the sleeve is forced longitudinally in onedirection, said instrumentalities as an organism being removablyconnected to the said sections of the alined shaftin and alinedtherewith'and the said removab e connections permitting the said clutchmechanism to be removed from the machine without ldisturbing therelation or alinement of the sections of shafting.
